Benefits of technology
The present patent relates to a roller leveler assembly for a cassette leveler. The assembly includes a drive mechanism with upper and lower drive shafts that can be supported by a support shaft during cartridge exchanges. The support shaft has saddles that guide the drive shafts in their movement. The technical effect of the invention is to enable the drive shafts to easily change position to accommodate different cartridges without the need for extensive adjustments.
Problems solved by technology
This method requires extra space (because of drive shaft length) and is more expensive because two (2) sets of drive shafts are required.

Embodiment Construction
[0030]The present disclosure relates to roller levelers. It finds particular application in conjunction with cassette roller levelers which have two different roll cartridges which have rolls of different diameters and different center distances. Specifically, the apparatus of the present disclosure is a drive shaft positioning support that supports and shifts the location of drive shafts during cartridge exchanges to match the roll centers of the particular cartridge being inserted.
[0031]In order to support the drive shafts, referring to FIG. 1, a preferred embodiment of the disclosure is shown. A positioning drive shaft support 10 includes two support shafts 16, 18, i.e., a first or upper support shaft 16 for supporting a first set of upper drive shafts 12 and a second or lower shaft 18 for supporting a second set of lower drive shafts 14. Referring to FIG. 2, upper and lower drive shafts 12, 14 are rotatably connected to a first cartridge or cassette 17 of work rolls 21 or to a s...

Abstract
A roller leveler assembly has a first cassette having a first set of work rolls of a first diameter and work roll spacing and a second cassette having a second set of work rolls of a second diameter and work roll spacing. A drive mechanism selectively drives one of the first cassette of the first set of rolls and the second cassette of the second set of rolls. The drive mechanism has a first set of upper drive shafts and a second set of lower drive shafts and a drive shaft support assembly. The drive shaft support assembly has a first support shaft for supporting the first set of upper drive shafts and a second support shaft for supporting the second set of lower drive shafts. The first support shaft and second support shaft each has a first set of saddles and a second set of saddles for supporting the first set of upper drive shafts and the second set of lower drive shafts in first and second positions corresponding to the work roll center spacing of the first set of work rolls and the second set of work rolls, respectively.
Description
CLAIM OF PRIORITY[0001]This application claims priority from provisional application Ser. No. 61 / 976,080, filed on Apr. 7, 2014, the entirety of which is incorporated by reference herein.BACKGROUND OF THE DISCLOSURE[0002]The present embodiment relates to roller levelers. It finds particular application in conjunction with cassette roller levelers which have and use two different roll cartridges or cassettes which have rolls of different diameters and roll center distances. An example of a roller leveler which may be used with the present disclosure is shown in U.S. Pat. No. 7,637,133 which is hereby incorporated by reference and will be described with particular reference thereto. However, it is to be appreciated that the present embodiment is also amenable to other like applications.[0003]Metal is formed into strips by a process known as rolling, wherein the strip is passed between a pair of work rolls of a rolling mill to reduce its cross-sectional thickness. In the process, the s...
